This aspirator allows users to collect specimens directly into glass vials that will later be filled with alcohol. Using this collecting method, specimens do not need to be transferred to other containers before alcohol is added. The aspirator has aluminum intake and exhaust tubes. Its neoprene stopper fits tightly into the glass vials. The mouthpiece is 1/4" (6mm) natural latex tubing and is protected with fine 220 mesh Nylon screen. The aspirator comes with two  4-dram capsule vials and 24mm polyseal caps.
